use bevy::math::FloatOrd;
use serde::{Deserialize, Serialize};
use leafwing_input_manager::prelude::*;

/// Doubles the input, takes its absolute value,
/// and discards results that meet the specified condition on the X-axis.
// If your processor includes fields not implemented Eq and Hash,
// implementation is necessary as shown below.
// Otherwise, you can derive Eq and Hash directly.
#[derive(Debug, Clone, Copy, PartialEq, Reflect, Serialize, Deserialize)]
pub struct DoubleAbsoluteValueThenRejectX(pub f32);

// Add this attribute for ensuring proper serialization and deserialization.
#[serde_typetag]

    fn process(&self, input_value: Vec2) -> Vec2 {

        // You can use other processors within this function.
        let value = DualAxisSensitivity::all(2.0).scale(input_value);

        let value = value.abs();

// Unfortunately, manual implementation is required due to the float field.
